Most individuals with spinal cord injury have neurogenic bowel dysfunction, which includes slowed colonic motility and has a significant impact on their health and quality of life. Bowel management typically includes mechanical rectal distension to evoke a recto-colic reflex and promote bowel emptying. Electrical stimulation could replace this mechanical distension. The purpose of this study was to determine the feasibility of evoking colonic activity using electrical stimulation. ⋯ Distal colon stimulation evoked colonic activity. The dependence of this response on stimulation location and anesthesia suggests that responses were reflex mediated. Colonic stimulation may have the potential to improve colonic motility for individuals with neurogenic bowel dysfunction.

The aim of this study was to report on the use of laparoscopic implantation of leads on the branches of the sacral plexus for neuromodulation in the treatment of chronic pelvic pain (CPP) in a multidisciplinary setting with the help of electrophysiological neuromonitoring. ⋯ This unique method is an alternative and effective treatment option for CPP even years after primary endometriosis surgery.

Review Meta Analysis
Placebo Response Rates in Electrical Nerve Stimulation Trials for Fecal Incontinence and Constipation: A Systematic Review and Meta-Analysis.
Successful treatments following electrical nerve stimulation have been commonly reported in patients with fecal incontinence and constipation. However, many of these nerve stimulation trials have not implemented sham controls, and are, therefore, unable to differentiate overall treatment responses from placebo. This systematic review aimed to quantify placebo effects and responses following sham electrical nerve stimulation in patients with fecal incontinence and constipation. ⋯ Sham stimulation is associated with clinical and statistically meaningful improvements in symptoms of fecal incontinence and constipation, as well as quality of life scores, highlighting the importance of sham controls in nerve stimulation trials. Noncontrolled studies should be interpreted with caution.

Randomized Controlled Trial
Transcutaneous Electrical Acustimulation Improves Gastrointestinal Disturbances Induced by Transcatheter Arterial Chemoembolization in Patients With Liver Cancers.
Gastrointestinal (GI) disturbances occur in patients who receive chemotherapy via transcatheter arterial chemoembolization (TACE) and could last for an extended period of time in some cases. Antiemetic drugs have a potential risk of developing hepatic failure and are ineffective for delayed nausea and emesis. Transcutaneous electrical acustimulation (TEA) has recently been reported to exert antiemetic and prokinetic effects, but it is unknown whether it has an ameliorating effect on TACE-induced GI disturbances. ⋯ TEA improves major TACE-induced GI disturbances in the delayed phase, including nausea, bloating, impaired gastric pace-making activity, and constipation in patients with liver cancers via the autonomic pathway.
